Determining the Techniques of Surveying and Cadastral Mapping in Vietnam

Abstract

Currently, the measurement of cadastral maps which serves for the land management is very important in Vietnam. Formerly, the measurement of cadastral maps in Vietnam is mostly done manually by measuring optical theodolite, and afterwards the map is drawn on the paper. Today with the development of new technologies, many technological applications are used for the measurement of cadastral maps in Vietnam. However, the measure of the cadastral map done by the electronic total station technology is the most popular because it is suitable for Vietnamese topographical conditions. The government of the state in regards to the land and the area needs to improve clearance, inspection and land dispute resolution.  In this method, the cadastral surveying is primarily used by the total station to measure direct in the field, then we use the specialized softwares such as MicroStation, FAMIS and Pronet to handle the measurement data and edit the map. In this study, cadastral mapping and measurement method for a particular area has found its conclusion. It is Cat Trinh Commune, Phu Cat District, Binh Dinh Province, Vietnam. The final result was the survey network diagram with 425 points including 24 high level cadastral points and the completed cadastral map with the total area of 4865.20 ha. There are 63 sheets in the cadastral map of Cat Trinh Commune which consists of 45 map sheets in scale 1: 2000, 18 map sheets in scale 1: 1000. All of them were stored as the digital files on the computer and the printed papers. Beside the cadastral maps, there are the statistical tables of the land area of each object and the purpose of the land use. This is an important document to help the State agencies to manage the land correctly, handy and consistently.
